Warne's late no-show fuels rumours

A press conference featuring cricketer Shane Warne has been cancelled at the last moment amid rumours he has split with fiancee Liz Hurley.

Cricket Victoria issued a media release cancelling Wednesday's event in Melbourne just 90 minutes before it was due to start, citing a "scheduling conflict".

There has been media speculation in recent days that Warne and Hurley have split.

The model did not send Warne a 44th birthday tweet on September 13, although she was in England and he was in Australia.

Warne's last tweet to his 47-year-old fiancee was on August 30, when he seemed to be making plans to spend a day at the races with her: "@simon_odonnell no worries mate ! Golf next week if you're free? @ElizabethHurley & my horse is still running, @HighclereRacing lift!"

The cricketer, a frequent tweeter, announced his split with wife Simone in 2010 on the social media platform.

Hurley and Warne have been engaged since September 2011.

After the press conference cancellation Warne tweeted: "Hey guys apologies about today & the late notice everyone! See you November 13 at the `G' we are all pumped & excited."

The media event, to launch the Shane Warne Foundation Ambassador Program, has been postponed until November 13.
